	Isn't it 22050? That would be half of 44100 :) And probably because it is mono. I could be mistaken...		Isn't it 22050? That would be half of 44100 :) And probably because it is mono. I could be mistaken...

	I'm not sure the audio sample rate is quite correct. I get slightly strange values like 44000 (logo_lucas.bik) and 22500 (AnivisionLogo.bik) on some of the samples provided, although I get sensible ones like 44100 (original.bik) on others... I'm not an audio expert by any means, but it seems strange that these values are so close to multiples of common audio sample rates and yet not equal to them. --[[User:DrV\|DrV]] 00:25, 6 January 2007 (EST)		I'm not sure the audio sample rate is quite correct.

Avenger teambg: suggested correction for bink container

suggested correction for bink container

New page

Original:
bytes 28-31 video frames per second
bytes 32-35 image format

Suggested:
bytes 28-35 video frames per second in a/b format (real number)
bytes 28-31 a
bytes 32-35 b

I noticed numbers like:
6025/201
2997/100
Both are very close to 30 (a usual framerate for videos)
